Harvesting Burls

A few weeks ago I noticed a fallen tree (maple, beech?) with 7 huge burls. I contacted the owner of the property and he was happy to let me take them. All I have is a small branch trimming chainsaw, but with some help from a buddy, we were able to get it cut up and brought back home - in two trips! I made a few small spoons from some of the smaller pieces. I hope to have a lathe soon and these will be exciting to turn.
